Scenario 1 : Off-network UE2UE link
SynchREF UE (UE1)
UE1(eth0 - 10.10.10.1)--------UE2(eth0 - 10.10.10.2)
UE1(eth0 - 10.10.10.1)--------UE2(eno1 - 10.10.10.2)
Here's an example of /etc/network/interfaces configuration for UE1

UE1 and UE2: Get and build vencore_app from d2d-l3-stub (branch: l3_stub)
- gcc -I . vencore_app.c -o vencore_app -lpthread
--------------------------------
TEST ONE-TO-MANY
Run UE1 then UE2, for example:
UE1: sudo ./lte-softmodem-stub -U --emul_iface eth0
UE2: sudo ./lte-softmodem-stub -U --emul_iface eno1
UE1: sudo ./lte-softmodem-stub -U --emul-iface eth0
UE2: sudo ./lte-softmodem-stub -U --emul-iface eno1
Test with Ping
- Sender - UE1: ping -I oip0 224.0.0.1
- Sender - UE1: ping -I oip0 224.0.0.3
- Receiver - UE2: using wireshark
Test with Iperf
- Sender - UE1: iperf -c 224.0.0.1 -u -b 0.1M --bind 10.0.0.1 -t 100
- Receiver - UE2: sudo ./mcreceive 224.0.0.1 5001
- Sender - UE1: iperf -c 224.0.0.3 -u -b 0.1M --bind 10.0.0.1 -t 100
- Receiver - UE2: sudo ./mcreceive 224.0.0.3 5001
Filter the incomming packets according to GroupL2Id: receiver (one-to-many) can discard the packets if it doesn't belong to this group.
For the moment, both sender and receiver use the same set of Ids (hardcoded)
UE1 (sender)
- sudo ./lte-softmodem-stub -U --emul_iface eth0
- sudo ./lte-softmodem-stub -U --emul-iface eth0
- ./vencore_app #send the sourceL2Id, groupL2Id to OAI
- ping -I oip0 224.0.0.1
- ping -I oip0 224.0.0.3
UE2(receiver)
- sudo ./lte-softmodem-stub -U --emul_iface eno1
- sudo ./lte-softmodem-stub -U --emul-iface eno1
#we can see the incomming packets from OAI log, however, cannot see from Wireshark -> they are discarded at MAC layer
- ./vencore_app #we can see the packets appearing in Wireshark
--------------------------------------
TEST PC5-S (UE1 -sender, UE2 - receiver)
TEST PC5-S (UE1 -sender, UE2 - receiver) and PC5-U for ONE-TO-ONE scenario
Configure UE1/UE2
UE1:
- sudo ifconfig oip0 10.0.0.1
- sudo iptables -A POSTROUTING -t mangle -o oip0 -d 10.0.0.2 -j MARK --set-mark 3
- sudo route add default gw 10.10.10.1 eth0

- sudo iptables -A POSTROUTING -t mangle -o oip0 -d 10.0.0.1 -j MARK --set-mark 3
- sudo route add default gw 10.10.10.1 eno1
step 1:
- UE1: sudo ./lte-softmodem-stub -U --emul_iface eth0
- UE1: sudo ./lte-softmodem-stub -U --emul-iface eth0
step 2:
- UE2: sudo ./lte-softmodem-stub -U --emul_iface eno1
- UE2: sudo ./lte-softmodem-stub -U --emul-iface eno1
- UE2: ./vencore_app -r #listen to incomming message from PC5-S
step 3:
- UE1: ./vencore_app -s #send a message via PC5-S (e.g., DirectCommunicationRequest)
Generate unicast traffic
UE1: ping -I oip0 10.0.0.2
--------------------------------------
TEST PC5-D
step 1:
- UE1: sudo ./lte-softmodem-stub -U --emul_iface eth0
- UE1: sudo ./lte-softmodem-stub -U --emul-iface eth0
- UE1: ./vencore_app -d #send a PC5-Discovery-Announcement via PC5D
step 2:

- UE2: sudo ./lte-softmodem-stub -U --emul-iface eno1
- UE2: ./vencore_app -d #send a PC5-Discovery-Announcement via PC5D
